Us time magazine voted for 2011 top ten medical breakthroughs

Newspaper reporter Chang Lijun viewpoints magazine recently announced the 2011 comprehensive foreign news agencies today top ten medical breakthrough results, cover the cloning of stem cells, the fight against major diseases, diet and other extensive fields of medical branch, recorded over the past year the human knowledge of their secrets and fight against the most terrible disease of the fruitful results achieved on the road.  1. using the New York stem cell Foundation for research scientists using cloning technology to produce stem cells improved the "somatic cell nuclear transfer" (SCNT) technique, the adult cell DNA (deoxyribonucleic acid) and eggs in the fusion of genetic material, to help cells split successfully turn stem cells, may help in the future humans ultimately cure spinal nerve injury or Parkinson's disease. "Somatic cell nuclear transfer" is the genetic material used in skin cells the mature egg cell DNA in somatic cells to replace, then clone "than" technology of the sheep.
Preliminary experiments on human cells fail, but the new study found that the appropriate genetic material seems to be in the reserved egg cells will help smooth divisions, which in turn produces stem cells. cells that are not on the general meaning of stem cells, their internal retained chromosomes also contain eggs. then scientists will attempt to suppress extra chromosomes or simply removed from the stem cells from them.  2. first developed the first malaria vaccines for malaria vaccine has been successfully tested in sub-Saharan Africa's children, this is the first such vaccines of human development. Researchers in sub-Saharan Africa has chosen 11 places, for the local children are vaccinated. results show, known as RTS,S malaria vaccine for babies aged 5 months to 17 months of the effective rate of approximately 56%, they have not been within one year after inoculation of malaria infection. in the area of prevention of serious infections,
The effectiveness reached about 47%. but the current tests are not comprehensive enough, researchers in further investigation.  3. anti-HIV drug treatment and prevention of Truvada antiretroviral drugs can reduce not only infected with HIV (human immunodeficiency virus) levels in patients with virus, it can also help an uninfected healthy people to prevent HIV infection.  United States Washington University on 4,758 on specific love partner expand has followed, these partner are is party for HIV positive and another party is not. 3 years Hou of results display, and taking comfort agent of controlled group compared to, taking anti-RT virus drug of partner infection rate reduced has about 73%. another a item by United States disease prevention control center leadership of research on 1200 name sex life active of health men and women for has investigation, found taking Truvada can makes HIV infection of risk reduced about 63%. Truvada was gay
Tested, was rated the top ten last year because the results are obvious medical breakthrough of the first, but the researchers said more study is required to determine its benefits for the prevention of HIV. it is clear that two breakthrough let it wins again this year.  4. the United States to impose new dietary guidelines in June this year, United States Government released according to the latest diet advice programme "my dinner plate", replacing the previous "food pyramid" diet composition layout.  Updated once every 5 years, the latest version was released in January this year. new guide encourages Americans appropriate reducing the amount of food intake, and recommends a reduction of added sugar, salt and fat, to better balance calorie intake and consumption, while encouraging people to eat more vegetables, plant foods and marine products, and moderate physical exercise. Circular plate more intuitive than the triangular pyramid. " My dinner plate "is divided into 4: one half is fruit and vegetables occupy the other half is a cereal and meat protein
Mass food. United States health officials hope that it helps to guide United States citizens to adopt a more healthy way of eating 5. cultivating human organs in the lab in March this year, United States via Wake Forest Institute for regenerative medicine, Dr andongni·Atala in the lab grown a human urethra with functional activity.  To made out a new urethral, attalla Dr first with biological may degradation material making has a tube shaped bracket, then will patients of bladder cell transplantation up, let they along bracket growth. research personnel will eventually generated of artificial "organ" transplantation back patients body, found it can normal operation discharges urine liquid. but the technology by needed material and device inputs on up to 5,000 dollars, cost too high, in at this stage also cannot universal. 6. mysterious close connection between bacteria and colon bowel cancer is caused by bacteria do? October this year, the discovery of two research teams reported almost the same: a normal
Human intestinal rare Fusobacterium named Fusobacteria seemed to be unusually active in colon cancer cells, and with a higher incidence of dependency.  The researchers found, compared with the healthy colon, bacteria are significantly more likely to occur in cancerous cells, which in some cancerous tissue samples and even the number of times higher than in normal tissues.  7. new weight loss drug called "Qnexa" experimental drug shows it can let users in about 1 year 10% reduction of weight. This drug actually is two species existing drug, is weight loss drug Phentermine and anti-epilepsy drug supporting effects ester of distribution products. which Phentermine can suppression human of hunger sense, supporting effects ester can help balance human brain within of neural signals contact, also can suppression people of appetite. but doctor also needs more data to confirmed this new drug of security and validity, United States Federal food and drug authority (f
DA) has rejected such request to market for new drugs.  In addition, there is a cancer research-based injection called adipotide, to allow patients to lose weight in a month 11%.  8. dog dogs can sniff out lung cancer may become the latest weapon of doctor detect cancer. Germany researchers training 9 months later, allowing them to identify respiratory samples for lung cancer patients and healthy people and found identification accuracy rate of up to 71%, and able to pick out in mixed sample 93% sample of health.  Scientists believe that dogs can tell in the breathing gas to some volatile components of micro-changes, inside the body content of the chemical composition of cancer patients may have changed. perhaps we will be able in the future by examining the patient's breath component to filter the cancer patients, but it is not possible to confirm this point. 9. the saliva analysis and identification of the deceased United States University of California at Los Angeles, scientists found that analyses in saliva
Genetic composition will probably help forensic for death age of information.  Research personnel found, saliva in the of external causes changes, as a a people of diet habits, and pressure status, and Sun sunlight of time, and contact carcinogenic substances even toxic substances of degree,, although does not led DNA itself occurred changes, but will in chromosome surface left traces, effect gene of opened and close. in chromosome some specific location Shang, this traces will rendering out like rings as of overlay or cuts, this a features will is expected to help expert judgment deceased of age, errors does not over 5 years.  10. blood tests predict heart disease and cancer risks Sweden Uppsala University researchers in August this year, according to the report a simple blood test may predict who might die of heart disease or cancer. Researchers found that the body contains a higher level of cathepsin s people than the lower levels of the enzyme in the body of the people is much higher probability of dying. this
High enzyme content in the adipose tissue, and it is generally recognized in the obese individuals are at higher risk of cardiovascular disease is consistent. Although it is not aware of this early mechanisms of enzymes in cardiovascular disease and cancer, but pharmaceutical companies is now in full swing to explore methods of inhibiting this enzyme. hot international navigation hot international navigationSweden century explorers on foot on the tree House Hotel European nostalgia train Malaysia Customs Ryukyu Royal families of ancient tombs
